Hi Stu,
I realize you are trying to get your own ram disk to work, but if you want to get a baseline you can use one we have on our wiki site, at http://xilinx.wikidot.com/open-source-linux, under Files To Download. This is the same ram disk that is included in the ELDK. This is the ram disk that I use to test the ML507 design in our Git tree. I also use NFS a lot for testing. Looks like you're close with yours, but I'm certainly no expert in that area as I typically have something that works and don't change it. Good luck, John ________________________________ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Stu Bershtein Sent: Tuesday, August 12, 2008 5:28 PM To: [email protected] Subject: ml507 initrd problem I have been trying to boot linux on an ml507 board for a few days now. I am using xilinx's linux-2.6-xlnx.git kernel. The rootfs is home rolled. I have had experience with NFS mounted root filesystems (not an option here), cramfs, and romfs but have never tried running root out of a ramdisk. Because of that I am quite sure I have dorked this up. Any help will be appreciated! I have added printk's in the kernel at do_sys_open to get an idea what is going on. Here is a snip of the boot output: . Kernel command line: console=ttyS0,9600 ip=on init=/linuxrc root=/dev/ram rw ram disk_size=9000 . Serial: 8250/16550 driver $Revision: 1.90 $ 4 ports, IRQ sharing disabled 83e00000.serial: ttyS0 at MMIO 0x83e00003 (irq = 16) is a 16550A . eth0: XLlTemac: Send Threshold = 0, Receive Threshold = 0 eth0: XLlTemac: Send Wait bound = 0, Receive Wait bound = 0 IP-Config: Incomplete network configuration information. open /dev/ram fd 0 open /initrd.image fd 1 RAMDISK: Compressed image found at block 0 VFS: Mounted root (ext2 filesystem). Freeing unused kernel memory: 144k init open /dev/console fd 0 code 10000000 - 1019854c, data 10195000 - 1019854c, stack bf85df00 open /dev/null fd 3 open /etc/inittab fd 3 And it gets very quiet at that point. The kernel is still running in ppc44x_idle. Does this suggest anything to anyone? I'll be more than happy to send or describe any config files to any one who might take pity.
